tabBarOnPress 在 react-native 中的反应导航选项卡中不起作用

Question

我正在使用嵌套导航抽屉>选项卡>堆栈导航器。

导航器正在工作，但是当我点击选项卡项时，它会抛出以下错误

undefined 不是一个对象（评估 '_ref4.route'） _getOnPress TabView.js:110:44 _handleOnPress TabBarTop.js:127:31 onPress TabBar.js:466:33 _callTimer JSTimers.js:156:15 呼叫计时器 JSTimers.js:411:17 __callFunction 消息队列.js:302:47 消息队列.js:116:26 __警卫 MessageQueue.js:265:6 callFunctionReturnFlushedQueue MessageQueue.js:115:17

const Drawer = DrawerNavigator({
    DrawerItem1: {

        navigationOptions: {
            drawerLabel: "Drawer Item 1",

        },
    },
    DrawerItem2: {
        screen: stackNav,
        navigationOptions: {
            drawerLabel: "Drawer Item 2",
            drawerIcon: ({ tintColor }) => <Icon name="rocket" size={24} />
        },
    }

Answer 1

我在使用 TabNavigator 时遇到同样的错误。

我还执行了官方的 react-navigation 示例 (https://github.com/react-community/react-navigation/blob/master/examples/NavigationPlayground/js/SimpleTabs.js)，但没有成功（同样的错误）。

我的猜测是这是最新版本的 Expo/React Native 的错误。

你用的是什么版本？

我正在使用：

"dependencies": {
    "expo": "^22.0.2",
    "react": "16.0.0-beta.5",
    "react-native": "^0.49.5",
    "react-navigation": "^1.0.0-beta.20"
  }

已确认：从 Create React Native App 中弹出可以解决问题。 因此，这似乎是 Create React Native App 或 Expo 上的一个错误。
